Abstract

A geometrically similar scaling was made from smallscale specimen to fullscale stiffened panels and then their collapse behaviour is investigated It is considered that the stiffened panel compressive ultimate strength test was designed according to geometrical scaling laws so that the output of the test could be used as representative of the stiffened panels of the compressive zone of a tanker hull subjected to vertical bending moment The ultimate strength of a tanker hull is analysed by a FE analysis using the experimentally developed master stressstrain curves which are obtained by the beam tension test and the compressive test of the stiffened panel and are then compared with the result achieved by the progressive collapse methodMingcai Xu got his BSc in 2000 and MSc in 2003 degrees at Wuhan University of Technology and is now a PhD student in Naval Architecture and Marine Engineering at Instituto Superior Técnico Technical University of Lisbon Portugal funded by the Portuguese Foundation for Science and Technology His current research interests include ultimate strength and reliability of ship structuresYordan Garbatov is Associate Professor at Instituto Superior Técnico Technical University of Lisbon Portugal and he is a leading researcher at the Center of Marine Technology and Engineering He has been involved in many research projects related to risk based maintenance assessment fatigue and ultimate limit state analyses and in the development of probabilistic age related damage modelsCarlos Guedes Soares had his postgraduate education at the Massachusetts Institute of Technology and the Norwegian Institute of Technology He is Professor of Naval Architecture and Marine Engineering and President of the Centre for Marine Technology and Engineering CENTEC a research center of the Technical University of Lisbon that is recognized and funded by the Portuguese Foundation for Science and Technology He is presently an invited Professor of the Shipbuilding College of Harbin Engineering University
